POWER MECHANISM FOR CHURNS.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed September 26, 1906. Serial No. 336,286.

To (all whom it may concern:

Be it known that I, HENRY F. CARRIoo, a citizen of the United States, residing at Paducah, in the county of McOracken and State of Kentucky, have invented a new and useful Power Mechanism for Churns, of which the following is a specification.

The invention relates generally to churns, and more specifically to mechanism for actuating the paddle of the churn, which mechanism is of the manually-actuated type and adapted to be operated by hand or foot power, or both.

The invention has for one of its objects to improve and simplify the construction and operation of apparatus of this character, so as to be inexpensive and easy to manufacture, reliable and ellicient in use, and requiring comparatively little power or effort on the part of the operator.

A further object of the invention is to pro vide an operating mechanism having features that readily adapt it to churns having paddles of either the oscillating or reciprocating type. 7

Another object is the provision of a driving mechanism for the paddle or dasher in which power is applied only in one direction of the operator, automatic means being included in the said mechanism for returning the dasher to its initial position, thereby relieving the operator of a great amount of work.

With these objects in view and others, as will appear as the nature of the invention is better understood, the invention comprises the various novel features of construction and arrangements of parts, which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate certain of the embodiments of the invention, Figure 1 is a perspective view of a churn provided with a power mechanism adapted to an oscillating or backandforth rotary dasher. Fig. 2 is a fragmentary perspective view showing a modified form of mechanism adapted for use in connection with a reciprocating dasher.

' Corresponding parts in both figures are indicated throughout by similar characters of reference.

Referring to the drawings, 1 designates the base of the supporting-frame, on which are secured two spaced parallel uprights or chambers 2, braced and spaced apart by the cross-bars 3. The lower ends of the standards 2 are set in notches 4 on two opposite sides of the base 1, the supporting-frame being firm and substantial.

The operating mechanism compr ses a vertical spindle 5, extending through central openings in the cross-bars 3 and suspended from its top end by the bearing 6. The spindle is mounted to have rotary motion, but prevented from moving longitudinally. Any suitable means may be provided for pre-. venting longitudinal movement of the spindlesuch, for instance, as the shoulder 7, that engages the under face of the top crossbar, and the bearing 6, arran ed on the top side of the cross-bar. The sioulder 7 prevents the spindle from moving upwardly, while the bearing 6, which is preferably of the p ball-bearing type, prevents the spindle from moving downwardly. The spindle 5 is provided with a thread 8, which is of comparatively coarse pitch, so that a nut traveling axially of the spindle on the thread can rotate the spindle with comparatively little friction. This nut or threaded portion that is adapted to engage the thread 8 is indicated at 9 on a horizontally-extending depressible bar 10. The ends of the bar 10 extend into vertically-disposed grooves 11, provided in the standards 2 at a point adjacent the lower cross-bar. These grooves serve as guides for the depressible bar 10 and also prevent the same from turning by the reacting thrust between the worm or thread 8 and nut 9. The bar 10 may be actuated by a treadle movement or by .hand, or both. For this purpose the bar 10 extends at its ends through the vertical guide-grooves 11 and terminates in handholds 12, that are located on opposite sides of the frame, so as to be conveniently gripped one in each hand. When foot power is also to be used, the bar 10 is suitably connected with the treadle 13, 'hingedly connected to the base 1.

The operating connection between the treadle and bar 10 comprises a cord 14, extending upwardly from the treadle, and a rearwardly-extending arm 15 on the bar 10 and connected with the said cord. In order [0 5 to prevent the bar from having a tendency to turn and bind in the grooves 11 by the op eration of the foot mechanism, a brace 16 extends froin the outer end of the arm 15 and sleeves at 17 on the spindle, thereby assisting no 5 tub on the churn-frame.

to guide the movement of the depressible cross member 10. Thus it will be seen that the spindle 5 can be conveniently rotated back and forth or oscillated either by hand or foot power, or both, according to the de-,

side of the member 10, and the said member is adapted to be depressed by the operator. If desired, however, the arrangement may be reversed, so that the power-stroke is required to be done by the operator pulling upwardly on the member.

' The churn-tub or cream-holder 19, which may be of any approved form, is adapted to rest on the base 1 and is provided with a dasher adapted to have a back-and-forth rotary movement. The shaft 20 of the dasher extends upwardly through the top of the holder 19 and is preferably detachably connected at the lower end of the spindle 5, so as to facilitate the placing and removal of the For this purpose a coupling-sleeve 21 is feathered on the lower end of the spindle 5 and at its bottom portion has a squared end arranged to fit in the squared end 22 of the dasher-shaft. Thus by lifting the coupling-sleeve the shaft is disconnected from the spindle, and by lowering the sleeve when the churn is properly placed the shaft will be connected with the spindle, so as to receive rotation therefrom.

In the modified form of the invention shown in Fig. 2 the power mechanism is the same as that hereinbefore described, except that the screw and nut are dispensed with and a reciprocating spindle 23 substituted for the spindle 5 of the previous construction. The reciprocating member 23 moves up and down in the bearings 24 of the cross-bars 3 and is rigidly connected with the actuating member 10. The lower end of the member 23 is provided with a coupling-sleeve 25, swiveled on the said member and provided with a sloping slot 26, in which it is adapted to interlock-the pin 27 on the dasher-shaft 28. By this means the dasher and reciprocating member are suitably connected, so as to move up and down together or to be detached in a convenient manner. The con struction and operation of the hand and power mechanism used in connection with this modified form are the same as that described in connection with Fig. 1, so that further explanation is deemed unnecessary. The upper end walls 29 of the guide-slots 11 limit the upward movement of the actuating bar 10. Furthermore, they serve as abutments engaging the said bar, so that the churn device as a whole can be picked up by the handholds 12 and carried from place to place as occasion requires.

From the foregoing description, taken in connection withthe accompanying drawings, the advantages of the construction and of the method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have'described the principle of operation, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative and that various changes may be made when desired as are within the the scope of the invention.
